Surface Treatment Of Rail Shoulder

The rail shoulder is an important part of the railway track, and surface treatment of rail shoulder method has an important impact on the service life and safety of the track. Next, let’s take a look at the common rail shoulder surface treatment methods.
Heat treatment: The rail shoulder surface can be hardened through heat treatment to improve its wear resistance and fatigue resistance. Commonly used heat treatment methods include quenching, tempering, carburizing, etc.
Shot peening: Shot peening is a surface strengthening treatment method that sprays metal projectiles onto the rail shoulder surface through high-speed airflow, causing cold work hardening on the surface, thereby improving its wear resistance and fatigue resistance.

Coating treatment: The rail shoulder surface can be covered with a layer of high wear resistance and high hardness coating through coating treatment method, thereby improving its wear resistance and fatigue resistance. Commonly used coating treatment methods include electroplating, spraying, thermal spraying, etc.
Laser cladding: Laser cladding is a surface modification technology that uses a high-energy laser beam to fuse the rail shoulder surface and alloy powder together to form an alloy layer with high hardness and high wear resistance, thereby improving its wear resistance. resistance and fatigue resistance.
Ion implantation: Ion implantation is a surface modification technology that injects high-energy ions into the rail shoulder surface to form a surface layer with high hardness and high wear resistance, thereby improving its wear resistance and fatigue resistance. performance.
In short, the surface treatment of rail shoulder method needs to be selected according to different use requirements and material selection. Correct surface treatment methods can improve the service life and safety of the rail shoulder while extending the service life of the track. With the continuous development and advancement of technology, it is believed that more advanced, environmentally friendly and efficient rail shoulder surface treatment methods will be widely used in actual construction in the future.
